What does "teamwork" really mean?

So I've been thinking. A couple of doctors left our unit and they had very kind and enlightening words of departure. They've really noticed how well teamwork nursing works and how it really benefits patients. To me, teamwork means being able to effectively communicate and work with doctors (and other disciplines such as the dietician and physiotherapist and occupational therapist) to ensure awareness of critical patient assessments and to promote effective interventions which can ultimately lead to faster recovery times or optimal outcomes. They have certainly reinforced my pride in my chosen profession and have added to my confidence in my own practice! They will be missed.
